Application filed April 21, 1923. Serial No. 638,611. Our invention relates to improvements in ing. These joints will form a fluid hollow structures and to the method of makclosure between the adjacent sections. ing such structures. We aim to provide a In Fig. we have shown a multiple cellustructure which can be made of flanged memlar structure formed of a series of H-beams I bers such as rolled H-beams, channel bars, 8 and channel sections 6 as shown in Fig. 2. so Z-bars, I-beams, angle bars and the like. This structure provides a series of fluid tight The invention is illustrated in the accomchambers '16, the structure being madeu of panying drawings in which a number of identical units each of w 'ch F'g. I shows a pair of H-beams placed comprises an H-section 8 and two channel alongside each other ready to be united; Sections 6 as arranged in Fig. 2. The chan- 55 Fig. 2 is a, similar view illustrating an H- nel sections 6 being joined web to web. This beam and a pair of channel bars arranged to forms a wall 6 of double thickness between be united to the flanged H-beam; certain of-the chambers 16.

While it is preferred to build our structure from rolled sections we do not limit ourselves thereto as it is clear that pressed or forged metal sections of various configurations may be employed. 7

While we have described with great particularity specific embodiments of our invention and the method of production is not to be construed that we are limited thereto as changes may be made by those skilled in the art without departing from the invention as defined in the appended claims.

' What we claim is 1. The method of making a multiple cellular structure for the circulation of fluids,

which consists in arranging rolled structural steel H- hapes or the like adjacent to one another with the edges of their flanges abutting and electricall welding such edges together to form a flui -tight structure with adjacent cells which are separated from one another by single webs of said sha es.

2. The method of makinga cellu ar structure for the circulation ofqfluids, of the widthof onetcell and the length of a plurality of cells. which consists in arranging rolled structural steel flanged shapes adjacent to one another in serial arrangement with abutting flanges and with webs forming partitions of single thiclmess between successive cells, and electrically welding such edges to form a fluid-tight structure of the character described.

3. A multiple cellular structure for the circulation of fluids comprising rolled struc tural steel H-shapes or abutting and integrally united to one another to form a fluid-tight structure with adjacent cells which are se arated from one another by single webs 0 said shapes. 4. A cellular structure for the circulation of fluids, of the width 9f one cell and the length of a plurality of cells, comprising rolled structural steel flanged shapes adjacent to one another in serial arrangement with abutting another and with webs forming partitions ofsingle thickness between succemive cells. In witnessiwhereof. we have hereunto signed our names.
